Possible problem with Calc formula bar

Not sure if this is a problem or not, In Calc the following issues have been observed:

  1. in the formula bar the numbers such as 1 and 3 have the first half obscured (not showing) almost like they are over lapped by another box, the default font is Liberation Sans font size 10
  2. This has been observed in the drop down box that shows the font size also, the number 1 of font size 10 is only half visible it is almost like it is far to left
  3. I have also noticed it in font size list in the format cells dialog box
